Tech's gender and race gap starts in high school

When people talk about how to diversify the tech field, a common solution is, "Start earlier." Rather than focus on getting women and minorities hired at tech startups or encouraging them to major in computer science in college, there should be a push to turn them on to the discipline when they're still teenagers—or even younger.

"It's already too late," Paul Graham, founder of the tech entrepreneur boot camp Y Combinator, said last month in a controversial interview. "What we should be doing is somehow changing the middle school computer science curriculum or something like that."

Right now, the "start early" strategy doesn't seem to be working: The students doing advanced computer science work in high school remain overwhelmingly white and male. According to data from the College Board compiled by Georgia Tech's Barbara Ericson, only a small percentage of the high-schoolers taking the Advanced Placement Computer Science exam are women. Black and Latino students make up an even lower percentage of the test-takers.
